An unannounced upper mid-range Android smartphone from Lenovo has appeared on the Chinese TENAA website. Dubbed the X2, the smartphone has passed certification in the country and has revealed a decent sounding specs sheet in the process.

The Lenovo X2 will be available in two versions with model names X2-CU and X2-TO. The X2-CU is powered by an octa-core CPU, presumably residing in either a MediaTek or the company's in-house Kirin 920 chipset, while the X2-TO packs a 2.2GHz dual-core processor. This is the only difference between the two as both feature a 5" 1080p display, 2GB of RAM and 32GB of storage.

At the back, both Lenovo X2 versions feature a 13MP snapper with LED flash and a 5MP front-facing camera. Their dimensions are 140.2 x 68.6 x 7.27mm and the overall design is a bit reminiscent of Sony's Xperia Z-series of phones.

With the certification process done with, Lenovo should launch the Android 4.4 running phones soon enough. Nothing particular has been hinted by the manufacturer, but the IFA 2014 which is starting next week would be a convenient occassion.
